* - add lk_flags in fuse_lk_in | |
* - add lock_owner field to fuse_setattr_in, fuse_read_in and fuse_write_in | |
* - add blksize field to fuse_attr | |
* - add file flags field to fuse_read_in and fuse_write_in | |
* | |
* 7.10 | |
* - add nonseekable open flag | |
* | |
* 7.11 | |
* - add IOCTL message | |
* - add unsolicited notification support | |
* - add POLL message and NOTIFY_POLL notification | |
